'LID FOR JOURNAL-BOXES.

Specification of Letters Patent.

Application filed January 9, 1906. Serial No- 295,295.

To all whom it may concern:

Be it known that I, THOMAS HARRISON SYMINGTON, a citizen of the UnitedStates of Ame ica, and a resident of the city of Baltimore and State ofMaryland, haveinvented certain new and useful Improvements in Lids for Journal-Boxos, of which the following is a specification.

My invention relates to a lid for a journal IO box designed to cover thefront opening of the standard Master Car-Builders journal box, to be soconstructed as to exclude dust at the hinge, and to be held in placeagainst its seat by the torsion of a spiral spring.

In the drawings similar reference numerals indicate the same parts ofall the fi ures.

I i ure 1 is a front elevation of the lid in osition upon the box. Fig.2 is a vertical ongitudinal section of the box and lid. Fig. .20 3 is alan view of the end of the box carrying the lid Fig. 4 is a horizontalsection of the lid through the line ;c-r of Fig. I. Fig. 5 is anelevation of the hinge pin or pintle. Fig. 6 is a perspective view ofthe torsion sprin in the position it occupies when in use and undertension.

Referring to the drawings. 1 is the box.

2 is'a tooled surface around lhc mouth of the box which forms the seatfor the lid.

3 is a lug cast upon the top edge of the box and to which the lid ishingwd. This lug is constructed as shown in Fig 3, partly in full andpartly in dotted line, having a central portion which is parallel to thelid, and two supporting portions 4 4 at right angles thereto.

The lugs 13 and 4 are perforated horizontally for the admission of ahinge pin or pintle 5. The rear surfaces of the lugs 44 are curved upona circle whose center is somewhat forward of the center of the 'pintle5, so that as the lid which is bent (lowninto close contact with the toof thelug when in contact with its scat wi l clear the rear surface ofthe lugs 4-4 as it is o cried and avoid friction. The sides of the ugs4-i are beveled from the front rearwardly for the same pur pose. Thefront edge of the lug 3 forms a cam surface for contact with the spring.by which the lid is held upon its seat.

6 is a vertical portion, having a small area. 7 is a curved portion,struck from about the same center as that of the rear surface of thelugs 44, that is to say, the center of which is in advance of the centerof the pintle 5. The maximum point of tension of the spring is attainedwhen the shoeis in contact with the upper edge of the cam surface 6.

8 is the id, provided upon its interior face with a machined surface 9-9 which makes contact with the seat 22 of the box to close theaperture.

10 is a flange, extending at right angles from the interior face of thelid, just inside of the machined surface 9 on the bottom and two sides.m

In the center of. the lid 8, there is a raised portion or housing11,.designed to contain the coils of the sprin abov which is a housing12.which covers t 1e lugs 3 and 44.

1 313 are hinge lugs cast integral with the the lid on each side of thehousing 12 and which are provided with central perforations to admit thepintle 5. Upon the rear edge of the housing 12 is a li -14c, which, asshown 1n Fig. 6, stands imme iately over the pintle and contacts withthe top of the lug 3.

and the lugs 44. The cover or lid is made of malleable material, andwhen the lid is in the position shown inFig. 6, thislip 14 is hammereddown into close contact with the top of the lug 3 so as to make apractically dust (proof joint. This close joint is preserve by the factthat the curves of the rear surfacespf the lugs 44 are struck from acenter in advance of the center of'the intle 5 sothat the moment the lidis raised t e lip 14 begins to clear and friction with the lugs 3 and4-4 is prevented.

l515--are lips, semi-circular in form,- w lneh project from the rearedges of the hinge lugs 13l3 of the lid, and stand opposite to theinclined surfaces of the lugs 4-4. When the lid is placed in positionupon the box, these lips l5-15 are hammered down against the curves ofthe lugs 44, so as to make a practically dust proof joint therewith. Asthe lid is raised the bevel of the lugs, shown in full and dotted linesin Fig. 3, will cause the lips 1515 to clear said bevel surfaces andmove freely without contact therewith. The bevel surfaces will permitthe lid to be raised to a position where there IS a clearance, and then,when the lips 1515 are hammered down into contact with the bevelsurfaces, these lips will bend, and bear and the housing 11 of the lidand the free ends 17 -17 are held firmly within the overhanging lugs1818 which are cast upon theinterior of the lid.

19 is a shoe, secured upon the loop of the spring to take the wear ofthe cam surfaces 6 The. spring must be placed under torsional tension inorder that it may be secured within the lid. The ends are pressedtogether so .as to engage the lugs 1818, and by their own elasticity,hold themselves in place. The

shoe 19 is then placed in contact with the point 6 of the lug 3, andpressure applied to,

bring the hinge lugs into register. This pressure will compress thespring into tension. The pintle 5 may then.be passedthrough the hinge,and its split end bent'and clenched upon the. recessed boss which formsone side of the ligl portion of the hinge so as to lock it in place andcause it to turn therewith. I 7

It will be noticed that this form of structure enables me to provide mylid with a long, flexible, torsional spring, having a large limitofelasticity and a consequent long life. It also provides a springwhieh isindependent and detachable, which may be replaced by another of the samecharacter on the road by any train hand. I

Having thus described my invention, what I claim, and desire to secureby Letters Patout is:

1. Ina journal box the combination of a hinged lid, an independenttorsional spring mounted upon the interior oi'the lid, but detachabletherefrom, although secured thereto, and which contacts with the camsurface upon the box to hold the lid upon its seat;

2. In a journal box the combination of a lid attached tov the box, witha torsional spring interposed between the lid and the box and a ham onone of said parts co-opcrating with the spring to hold the lid upon theseat.

3. In a journal box, the combination of a lid secured to the boxand-bearing upon a seat thereon, with a torsional spring one end ofwhich bears upon the box andaetingiupon a camon the box and the otherend upon the lid and holds the lid upon its'seat'.

' -4. In a journal box the combination of a v lid'which is hinged to thebox above the opening; a torsional spring attached to the interiorsurface of the lid, a cam surface upon. the box bearing upon the freeend of the" combination of a lid designed to close the opening hinged tothe box, the box portion" 0 the hinge being beveled away fromthe lidupon the sides, the lid portion of the hinge being provided with lipswhich may be; bent into contact with sides of the box por -1'3 vtionwhen the lid is closed, and which by virtue of the bevels of the sidesof'thc. box

portionwill clear them as the lid is openedi 7. In a journal box thecombination of a lid with a double torsional spring acting upon a cam onthe box, each leg being coded, and

bent so as to form a loop between them, the

free ends being so bent as to hold themselves-- in place by their ownelasticity.

8. In a journal box the combination wardly projecting hooked lu of a lidhaving a central housing and two in s the hooks'be"- ing locatedopposite each other, with a dollble torsional spring having a centrallip a'nd I 1 two coil legs, the coils of the spring being seated in thehousing of the lid and the free 1 legs of the spring being seated andheld by the hooks upon the interior of the lid, the-lip}- of the sprinbeing free to exert pressurcupon the box, su stantially as described.

9. A journal box lid hinged to the box, thei pintle of the hinge havingits free end] clenched upon the hinge lug of the lid, so as to be fastthereto and to turn therewith.

10. In a journal box the combination of a lid hinged thereto, by a lugon the box and two lugs on the lid, one of the lid lugs beings 9;provided with a ,notch on its exterior surface,"

and a pintle passing through the hinge lugs:

and having its free end clenched into the notch on the exterior of the.lid lug-, whereby the pintle will be secured in the hinge and hold fastto the lid.
